Chapter 17 Lesson 1 & 2 bio

Question 1

What the difference between Genotype and phenotype.

Answer 1

phenotype is physical and geneotype is genetic.

Question 2

Phenotypes are produced by genotype and what else?

Answer 2

the enviormennt

Question 3

Natural selection acts directly on

Answer 3

phenotype and genotype

Question 4

population

Answer 4

a group of indviduals of the same species that made and produce offspring.

Question 5

Gene pool

Answer 5

All the genes are present in a population

Question 6

Evolutioin in genetic form

Answer 6

a change in the allele frequencys within a population

Question 7

What are the 3 sources of genetic variation

Answer 7

mutation
lateral gene transfer
genetic recombination

Question 8

What is a diffrence between gene trait and polygenic trait

Answer 8

A single trait is controlled by one gene well polygenic traits are influenced by many genes.

Question 9

what is evolutionary fitness

Answer 9

a organism’s ability to survive succes on passing genes tp next generation.

Question 10

natural selection on single gene traits can lead to changes in - frequency

Answer 10

allele

Question 11

3 types of selection

Answer 11

directional
stabilizing
disruptive

Question 12

if a population is not evolving allele frequencies in its gene pool do not change, which means that the population is in-

Answer 12

genetic equilibrium

Question 13

five conditions that disturb genetic equilibrium and cause evolution.

Answer 13

mutations
natural selection
non - random mating
small populationg size
migration
